To reproduce: host a server that logs incoming requests (localhost is blocked), set it as your OpenAI base URL, and select Composer 2. This works for GPT and Claude models too. Composer 1.5 is the only model that blocks it.

Nice! Was what Composer 1.5 based on?

If this leak is true, this is very bad for Cursor.

Because Anthropic listed Moonshot AI (creators of the Kimi Models) as part of the 'distillation attack" campaign [0].

That's enough evidence for Anthropic to ban Cursor from offering Claude even when serving a competing model and I predict that Anthropic will ban them just like they did with OpenAI, xAI and OpenCode.
